How this service works
Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://preflight.agentdiet.dev/v1/dom-stripper)
Output
Returns a distilled representation of the webpage or HTML in the requested mode (markdown, structured JSON tables, skeleton outline, or BM25-ranked budget excerpt), along with an ROI proof object showing raw vs distilled token counts, compression ratio, tokens saved, and estimated LLM cost savings. Optionally includes billing details and cache hit/miss status.
Example use cases
Compress docs page for LLM context
“Grab the content from https://docs.openai.com/api-reference and distill it into structured markdown so I can fit it in my prompt without blowing the context window.”
Budget-focused excerpt for research query
“Pull the page at https://techcrunch.com/2024/05/ai-funding and give me only the parts relevant to 'Series A funding rounds', keeping the output under 800 tokens.”
Distill raw HTML pasted from a scrape
“I have raw HTML from a competitor pricing page — can you strip it down to just the structured pricing tables and metadata, ignoring all the nav and footer junk?”
Technical details
Endpoint
GEThttps://preflight.agentdiet.dev/v1/dom-stripper?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to read a webpage but must stay within a token budget, reduce LLM costs, or extract only relevant content matching a specific query. It is especially useful over raw HTTP fetch when the page is noisy with nav/footer/ads, when you need structured output from unstructured HTML, or when you want measurable compression metrics (ROI proof). Prefer budget mode with a BM25 query for targeted extraction from long pages; prefer markdown mode for general-purpose LLM ingestion.
Side effects
- URL is unreachable or returns non-200 status — fetch failure error
- URL parameter missing — validation error since it is required
- mode=budget used without a query parameter — may return unfiltered or error
- max_tokens set below minimum of 20 — validation rejection
- HTML payload too large — may timeout or exceed processing limits
- Paywalled or JavaScript-rendered pages may yield thin or empty content
- x402 payment failure — endpoint returns 402 if payment not resolved
